Out of Stock


Designed for Speed, Made to Win.​

From racing around the neighborhood to pro races on the track, speed is everything. The Polygon Razor is built for young racers ready to launch off the gate, carve corners with precision, and master manuals. With a lightweight alloy frame and razor-sharp handling, your kid is built to win.​

A Durable, Rigid, and Light Alloy Frame

This smaller version of the Polygon Razor features a well proven chainstay and a durable chromoly fork, giving young racers a stiff, reliable ride that can handle the rigors of racing. The zero-stack headset adds a sleek look and enhances front-end adjustability for precise control.

Low Rolling Resistance for High Speeds

Designed for young racers, the Polygon Razor’s 20 x 1-1/8 tires are lightweight and built for low rolling resistance, ensuring high speeds and momentum on the track.

No Slips, Just Speed

With its chain tensioner, it keeps the chain secure, prevents slippage, enhances drivetrain efficiency, and reduces wear—delivering smoother rides and better performance, especially on high-impact landings.

Tailored Combos for Ultimate Comfort

Each size features specially selected handlebars, chainrings, and crank arm length for optimal fit and performance.
